INKING MECHANISM FOR PRINTING-MACHINI ES.

SPECIFICATION forming part of Letters Patent N 0. 675,024, dated May 28,1901. Application filed July 25, 1900. Serial No. 24,843. "No model.

To (tZZ whom, it may concern:

Be it known that I, KURT SONNTAG, asubject of the German Emperor, and aresident of Leipsic, Germany, have invented certain new and usefulImprovements in Inking Mechanism for Printing-ll/lachines, of which thefollowing is a specification.

In the usually-constructed rotary and duplex printing-machines withrocking or oscillating printingu-ollers, such as shown, for example, inLetters Patent of the United States granted Julius Wezel on the 29th dayof June, 1897, and numbered 585,546, the in king-rollers are mountedabove the latter and,v cover, therefore, the printingplate, so that saidinking-rollers do not permit of easily removing and replacing theprintingplates. I am aware that various devices have been constructed totemporarily disengage the inking-rollers from the printingroller.However, such devices are not adapted to completely clear the space andgive full access to the pi'intingplates, so that the lat-- ter can onlybe removed and replaced with much trouble and great loss of time. Mypresent inventionhas for its object to remove these objections, as willbe readily understood from the improved construction hereinafter fullydescribed and claimed.

In the accompanying drawings, forming a portion of this specification,Figure l isa diagrammatical front elevation, and Fig. 2 is a sideelevation, of the improved inking mechanism, in combination with themain printing'rollers of a printing-machine.

Referring by letters to the drawings, A represents the main oscillatingor rocking roller of a printing-machine, arranged between the usualprinting-rollers B and O.

D indicates the frame ofthe machine, which is provided with rails E andF, extending on one side beyond the frame, as shown in Fig. 2. Uponthese rails is movably arranged the carriage G, carrying twolongitudinally-movable wedges H and J, adapted to be moved by actuatingthe feed-screws J and H. Said Wedges support a horizontal plate K,vertically guided in the frame of the machine. It will be seen that byrotating the hand-wheel L the wedges H and J are moved longitudinallythrough the agency of the gear-wheels L H J Secured on the horizontalplate K is a suitable frame N, provided with bearings for all theroller-shafts of the inking system and also for the shafts of theoperating gearwheeis R and R, normally meshing with the toothed rim S onthe main rocking roller A. When the plate K is lowered, the whole inkingmechanism is also lowered, whereby the gear-wheels R and R are broughtout of engagement with the toothed rim S of the main roller A, so thatthe carriage G may now be Withdrawn forwardly, together with the ink ingmechanism, for the purpose of easily cleaning and removing thei1'ikingrolle1's. When the inking-rollers are cleaned, the carriage G ispushed back into the machine,"

whereupon the inking mechanism is again raised by feeding the wedges Hand J until the upper inking-rollers are brought into contact with theprinting-plate and until the gear-wheels R and R mesh again with thetoothed rim S of the main roller A.

The advantage of the improved construction is that the space above themain rollers is completely cleared, so that the removal of theprinting-plates and corrections may be easily and readily effected. 'lheinking mechanism is readily accessible and may be easily adjusted whenthe supporting-carriage is withdrawn forwardly, as described.

Having fully described my invention, what I claim, and desire to secureby Letters Patent, is

1. The combination with the frame and main printing-rollers of aprinting-machine, of an inking mechanism, embodying a movable carriagerunning on rails arranged on der said main rollers, a vertically-movableplate supported on said carriage, a suitable frame secured on said platethe usual inking-rollers journaled in said frame, and means forvertically adjusting said plate, substantially as and for the purposeset forth.

2. The combination with the frame and main rollers of aprinting-machine, of an inking mechanism, embodying rails secured to theframe of the machine underthe main rollers thereof, said rails extendinglaterally beyond the frame of the machine, a suitable carriage adaptedto run on said rails, longitudinally-movable wedges on said carriage,
